Hyperbolic Slot

SKU Code: REMZ105

Can a straight rod pass through a curved hole? It is an interesting demo designed to try. A flat vertical plane made of plastic is mounted on a table top; there is a curve cut into the plastic sheet. As the rod is rotated around itself one cycle, the scanned area creates a 3 dimensional rotary surface called hyperbola and the rod draws a parabola. Therefore, it passes through the transparent surface smoothly.
